    I noticed a big flaw in the test case.

    right now the pattern ^(.{3}\.?){4}$ passes all the test case, but this violates the problem statement that the pattern needs to strictly follow a period after the first three charcters. for example "abcdefghijkl" passes the test, when it shouldn't.

    short solution not violating this constraint can be something like ^...(\....){3}$ which enforces the \.

    Requirements are ambiguous and the comma at the end of the instruction string is hard to see in the given font. I thought the text had to end with a period because the comma's tail is indiscernible (to me).

    I suggest restating the question such that it is more accessible to those with vision problems.

    regex_pattern = r"^...\....\....\....$"

import re
import sys

test_string = input()

match = re.match(regex_pattern, test_string) is not None

print(str(match).lower())
